Problem when running briefcase in dev mode – “ImportError: cannot import name ‘Environment’ from ‘System’ (unknown location)”
I am doing the BeeWare Python app tutorial, and I have made it to Tutorial 1 – Run the app in Developer mode, however I get an error and cannot figure out how to fix it. It should run in dev mode and open up a GUI window, and mine says starting in dev mode… but never opens a GUI window, it gives me this error message instead: ImportError: cannot import name ‘Environment’ from ‘System’ (unknown location)
Problem running app helloworld.
